I am getting ready to set up speakers in my home theater, and I recently bought a Klipsch R-120SW powered subwoofer, and a Denon x3700h AV receiver. My question is what should I set the Crossover on the back of the sub to? I have seen some places saying that connecting the sub to the LFE port on your receiver will make it so the receiver handles crossover, in that case set the dial on the sub to "Off" if available, or all the way up if not. Is that true, and if so does the Denon x3700h support LFE via the sub ports on the back? I noticed they aren't actually labeled LFE so I wasn't sure.

The receiver will control the crossover, so turn It off on the subwoofer.

These are the settings I have on my R-8SW, which is the downward firing variant of the R-120.

As John says above you want the receiver to control the LFE. To do that, set your Low Pass knob to the furthest right setting which is just straight LFE.

As for your Denon, plug an RCA cable from the port I've highlighted into the L input on the subwoofer and you should be good to go.

Oh do I need specifically an RCA cable? I was just going to run speaker wire with a banana plug, is this wrong?

Perfect, thank you and thanks for posting a picture of your setup. What is the auto/on/off switch for?

That's the power. People usually put it on Auto, then the sub turns on and off automatically when it senses or stops sensing a signal.

That switch is very sensitive btw. Its really easy to miss the auto setting and keep the subwoofer constantly on I've found.
